Abstract (en)
[origin: EP0306025A2] The present invention concerns a process for producing a polyarylene sulfide of high whiteness from an alkali metal sulfide and a dihalogenated aromatic compound, wherein a reaction product obtained by reacting alkali metal sulfide (M<2>2S) and at least one ingredient (M<1>X) selected from the group consisting of alkali metal halide and alkaline earth metal halide under the presence of water and polar solvent and separating by solid-liquid separation are brought into contact with a dihalogenated aromatic compound.
